Least Common Multiple of 280/29,427/77,687/81

Given numbers are 280/29,427/77,687/81

Formula to find LCM of Fractions is

LCM = LCM of Numerators/GCF of Denominators

As per the formula LCM of Fractions let’s split into two parts and find the LCM of Numerators and GCF of Denominators

In the given fractions LCM of Numerators means LCM of 280,427,687

Least Common Multiple of Numerators i.e. LCM of 280,427,687 is 11733960.

GCF of Denominators means GCF of 29,77,81 as per the given fractions.

GCF of 29,77,81 is 1 as it is the largest common factor for these numbers.

Lets's calculate LCM of 280,427,687

LCM of Fractions 280/29,427/77,687/81 is 11733960

7 280, 427, 687
40, 61, 687

∴ So the LCM of the given numbers is 7 x 40 x 61 x 687 = 11733960

Least Common Multiple of 280,427,687 with GCF Formula

Least Common Multiple of 280,427,687 with GCF Formula

The formula of LCM is LCM(a1,a2,a3....,an) = ( a1 × a2 × a3 × .... × an) / GCF(a1,a2,a3....,an) x common factors(if more than 2 numbers have common factors).

We need to calculate greatest common factor of 280,427,687 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(280,427,687) = 1

common factors(in case of two or more numbers have common factors) = 7

GCF(280,427,687) x common factors =1 x 7 = 7

LCM(280,427,687) = ( 280 × 427 × 687 ) / 7

LCM(280,427,687) = 82137720 / 7

LCM(280,427,687) = 11733960


Lets's calculate GCF of 29,77,81

∴ So GCF of numbers is 1 because of no common factors present between them.

Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 11733960/1

Therefore the LCM of Fractions 280/29,427/77,687/81 is 11733960
